Sharon Osbourne admits to 'flingy wingy' with Jay Leno

Sure enough, Sharon Osbourne, 60, lived up to her promise by dropping one heckuva a bombshell: She once had a fling with Jay Leno, before either of them were married to their current spouses.

"Let's cut to when I was 25. I had just moved to America. I didn't know many people. Remember 25, I had met my husband but we weren't together, we were just friends," Osbourne began.

"I'm here, I didn't have a boyfriend. I never did date a lot at that time anyways, because I was not very dateable.

"My friend worked at this place and said you have to come down to this club, where I work because it's full of men.

"So, I come down to this club and it is full of men performing. And this one person, I think he's very nice, very funny. So, I said to my friend, 'I like him,' and she goes, 'I've got his number.' So, I said, 'We are going to prank call him!'

"So, we prank called him, and he liked my voice. Then I kept calling. I said I had the wrong number, but I kept him talking with my English accent.

"One thing led to another … he came to my house and met me, and then we had a little fling. And the 'fling' was more 'fling' for me, and not 'fling' enough for him. Because a couple of months into it, he brought around his real love of his life for me to meet. She was lovely. He took me to Fatburger and they showed me around town … Seriously, I had never been to Fatburger and I loved it! They were so kind to me and continued a friendship over the years.
